| | | MB500 - sad NAD…
Sign in to disble this ad
Found a used #1 condition GK MB500 (for gigging atop my 212MBE) on MF for $375, it arrived today, but won’t power up. Tried different power cords, tried different outlets…
Any ideas? Having saved $125, should I look into having it repaired? Could it be something really simple?
I haven’t seen these on sale or used before, and I just don’t want to pay $500 if I don’t have to.
Thanks... |

Most repairs of MB500s require a new power module.

Thanks... | I received a MB210 off here and the same thing happened, I guess during shipping. I took it to the local GK repair and it turned out to be a solder came loose, might be worth a lookie to a gk repair center in your area? just an idea though i know I was a little upset when i first got my rig, but im very happy with it now.

Should I just ask them what they suggest? |

Maybe if they cut me a break, like 20% off a new one, it wouldn't be worth trying to get it repaired. |

| | | | The thing just doesn’t power up, but I’m thinking the power amp might be fine.
Would the module I need be expensive? |

| | | | I'd Return it. You should be able to get a NIB one for 10% off any day, or even 15 to 20% off at times. They almost always have a 10% off coupon any more. |

Or else just wait for a 15-20% off coupon to come or a 50 off or 100 off code and buy a brand new one.
